How to choose a 1 camera out of 2 cameras in the scene to align using CTRL + ALT + 0?
Solution:


Select the camera you want to align to the view port.
View > Cameras > Set active object as camera
Align the view you want in your view port and press CTRL + ALT + 0


It will align the camera made active to the view you wanted.

Thanks to Dan for pointing another thread that helped me get my answer.
